How to produce ultrafine density EVA foam

Fine-density EVA foam products profile has been a pursuit direction. Flatness is good, feel good, good printing effects, such as color and delicate advantages, Some EVA foam factories has been pursuing these advantage. However, the original formulation simply can not solve this problem.
In the development of other formulations, Mor Rubber & Plastic Foam inadvertently discovered the secret. But in theory, thrust reversers, This formulation can be theoretically xplained. The use of coarse pore foaming rapid decomposition of the blowing agent in foam and low bridge bridging agents to keep up with coarse holes thus formed. Conversely if possible, in both foam and bridging synchronization, then the cell naturally fine.Mor used the HJ-1000 or catalyst HJ-2000 as catalyst instead of zinc oxide and stearic acid and found that the catalyst has such a feature. When molten catalyst uniformly dispersed , while fully catalytic AC foaming agent in average, it will also reduce the negative impact on the occurrence of bridging bridging agent. So that the foam product has a good surface of the fine density.
